So how do you see this kind of lifestyle? Do you judge them as wrong because their reason is gambling, or do you respect it since everyone has their own way of finding happiness?
Well since they are gambling responsibly without getting addicted or borrowing money is fine. Honestly, I would boldly said that they are doing well because not all gamblers that can easily do this without getting addicted to gambling. However, just like they always said that gambling is a personal decision that is the real truth about it because as a gambler that knows what gambling is all about would always gamble responsibly because there is no amount of advice that can easily change a gambler if them didn't decide by themselves.
This is similar to what I said earlier on my first comment in this thread. As they are not trying to get back their losses through gamble but elsewhere it shows that they already know the risks involved in gambling. They know that trying to recover from their losses through gambling will make them lose more. But what they failed to understand is that gambling is not a legit means to make money, they might win some of their bets but they can always win.
